2010-02-08[SCSI] mpt2sas: Added phy_enable and set_phy_speed sysfs callback support.Kashyap, Desai3-17/+232
Added new callbacks phy_enable and set_phy_speed in the mpt2sas_transport_functions template. This will allow end user to enable/disable phys and change links rates using the SysFS interface. Current implementation only supports direct attached phys, but we could in the future add support for expander based phys. A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added; this wrapper function used to send request to controller firmware to modify the phys and link rates. A new subroutine _transport_find_local_phy was added; a function for easly obtaining the local phy object for direct attached. Example to disable a phy echo 0 > /sys/class/phy3:0/enable Example to enable the same phy echo 1 > /sys/class/phy3:0/enable Example to change the link rate to 1.5 #echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 1.5 Gbit Example to change the link rate to 3.0 #echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 3.0 Gbit Example to change the link rate to 6.0 #echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 6.0 Gbit Signed-off-by: Kashyap Desai <[email protected]> Reviewed-by: Eric Moore <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2010-02-08[SCSI] mpt2sas: Delete volume before HBA detach.Kashyap, Desai1-0/+17
The driver hangs when doing `rmmod mpt2sas` if there are any IR volumes present.The hang is due the scsi midlayer trying to access the IR volumes after the driver releases controller resources. Perhaps when scsi_remove_host is called,the scsi mid layer is sending some request. This doesn't occur for bare drives becuase the driver is already reporting those drives deleted prior to calling mpt2sas_base_detach. To solve this issue, we need to delete the volumes as well.

2010-01-18[SCSI] lpfc: restore MSI-X/MSI supportGeorge Kadianakis1-4/+4
A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts. This patch restores lpfc's ability to support MSI-X/MSI interrupts that the "Addition of SLI4 Interface - Base Support" patch [2] broke. It reestablishes MSI-X as the default interrupt method and in case MSI-X is not supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx. [1]: http://bugs.gentoo.org/show_bug.cgi?id=296319 [2]: commit da0436e915a5c17ee79e72c1bf978a4ebb1cbf4d [James Smart: Background: Nothing Broke. This was intended. We had originally enabled MSI-X by default, but in qualification within the last 12 months, we encountered a major catch-22: There were at least 4 platforms, from 2 major OEMs, that : - Say they support MSI-X - platform routines work and act as if they do. - We enable it, generate a test interrupt to check they really do deliver it, and it works. - But shortly after attachment, the system hangs or loses interrupts, resulting in a bad system behavior. Given the distro's picking up the 2.6.32 kernel, we had to stick with a default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get fixed. However, we're also now encountering platforms that require MSI-X and never INTx, so we must change. It's desired also for also for performance reasons. So - now (2.6.33) is the right time to re-enable MSI-X by default. ] [jejb: fix up comment on default values] Signed-off-by: George Kadianakis <[email protected]> Acked-by: James Smart <[email protected]> Signed-off-by: James Bottomley <[email protected]>

Further to the lsml thread titled: "does scsi_io_completion need to dump sense data for ata pass through (ck_cond = 1) ?" This is a patch to skip logging when the sense data is associated with a SENSE_KEY of "RECOVERED_ERROR" and the additional sense code is "ATA PASS-THROUGH INFORMATION AVAILABLE". This only occurs with the SAT ATA PASS-THROUGH commands when CK_COND=1 (in the cdb). It indicates that the sense data contains ATA registers.
